Abstract

Изобретение относитс к гидромеханизации и предназначено дл подводной разработки грунтов. Цель - повышение надежности работы устройства за счет уменьшени его износа. Устройство включает грунтопровод 1, закрепленный на раме, ковш 3 с пазами 4 в боковых стенках 5, водозаборник 10 и кольцевые инжекторы 12. В пазах 4 закреплены щитки 6 ротора 7, соединенные с лопаст ми 8. Лопасти 8 расположены в ковше 3 с образованием внутренних камер 9. Водозаборник 10 закреплен на раме. В пазах 4 размещены вкладыши. Кольцевые инжекторы 12 установлены на грунтопроводе 1. Вкладыши соединены с лопаст ми 8 с возможностью перемещени вдоль выполненых в них направл ющих. В боковой стенке 5 ковша 3 выполнены отверсти 14, 15, сообщенные с внутренними камерами 9. Отверстие 14 соединено с водозаборником 10, отверстие 15- с кольцевыми инжекторами 12. Через отверстие 14 вода заполн ет внутреннюю камеру 9, промывает ее и захватывает с собой частицы грунта. Щиток 6 через отверстие 15 выдавливает воду в кольцевые инжекторы 12. 5 ил.This invention relates to hydromechanization and is intended for underwater excavation. The goal is to increase the reliability of the device by reducing its wear. The device includes a soil pipe 1, mounted on a frame, a bucket 3 with grooves 4 in the side walls 5, a water intake 10 and annular injectors 12. The slots 6 of the rotor 7 are fixed to the blades 8. The blades 8 are located in the bucket 3 to form internal chambers 9. Water intake 10 is fixed on the frame. In the slots 4 posted inserts. The ring injectors 12 are mounted on the ground pipe 1. The inserts are connected to the blades 8 so that they can be moved along the guides made in them. In the side wall 5 of the bucket 3, holes 14, 15 are provided, communicating with the inner chambers 9. Hole 14 is connected to the water intake 10, hole 15- with ring injectors 12. Through the hole 14, water fills the inner chamber 9, washes it and takes particles with it ground. Shield 6 through the hole 15 squeezes out water in the ring injectors 12. 5 Il.
